Electrum Rings

Taken all the way down to base materials, one Electrum Rings is 2 crafting steps deep and needs 1 intermediate — Electrum Ingot ×1 — which resolves to 1 distinct raw material totalling 4 units, plus 10 crystals.

That bill outweighs 3,935 of the 13,602 recipes tracked here and 504 of the 2,216 Goldsmith ones, and 4,464 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 5 are burned by the intermediates, so the real crystal cost is 10 Wind Shard.

Every step is Goldsmith work, from a Lv 42 intermediate up to the Lv 43 finish, so one class covers the whole chain.

Its single raw material is gathered, and no spot for it is timed, so nothing in the tree waits on the Eorzean clock.

Electrum Rings is itself consumed by 3 further recipes, all of them Goldsmith recipes.
